Abstract :
The LTC3857 and LTC3858 are versatile low quiescent current (IQ), 2-phase dual output synchronous buck controllers that are ideal for applications demanding high efficiency and minimal power loss over a broad range of load currents, from virtually no load to many amps.
They feature a wide input supply range of 4V to 38V (40V abs max) that covers a broad range of battery chemistries and power sources.
Each output can be set from 0.8V to 24V (28V abs max).
